I just checked your post on the forum. I haven't been on lately. I think your situation is exactly what posts #13 & 14 said. It looks like a back flow valve. My trailer doesn't have that. As poster #8 said there is a vacuum breaker on the bottom of the shower hose that lets the water drain out of the hose when you shut off the water. But from looking at your first photo a previous owner took that off and did the bypass work. I understand why they would want to do that because when using the shower as an outdoor shower, when you shut off the water it drains onto the wetbath floor which is not all that good because then you have to dry off the floor. So if you get rid of the backflow remodel job be sure to get a new vacuum breaker for the shower hose. Jamie

I fixed it! You guys were right, apparently it was an addition to drain the shower and the valve was bad or stuck open. I tried to unscrew it and even though I couldn't get it out (those tubes are impossible to undue) it must have released it. Now it shuts off the intake and just allows for the water to go out. Not sure how long it will work without jamming again but now I know the problem. Thanks you all!

likely culprit - hard water clogging the works. Beat it with a hammer or disturb it in some way and voila!

Happy Showers!

Sounds like a "Red Green" repair--If it ain't broke, hit it harder!"

What version of Netbook did you get? Marie really likes her Asus.

Shower check valve...

I know that it's awfully late (9 years!) to reply to this thread but...

Our 2004 16' Bambi has EXACTLY the configuration shown in this thread's photo. We bought the trailer brand new, so this was not some sort of aftermarket mod.

The only justification for this check valve's (assuming that's what it is) existence has to be for draining the shower water lines. Specifically, to let escape any water sitting between the shower hose's own vacuum breaker and the cold supply line. It would only open when draining the trailer's water lines. At least how that's the only explanation I can think of.

Anyhoo, I'm absolutely sure the thing's developed a slow leak in our case, which is causing a slow leak all over our wet bath. The shower hot/cold valves are pristine, with new washers, so I'm eliminating them from consideration.

My question: where to get one of these things?
